Sen. Robert Menendez slammed accusations that he had paid a Dominican woman for sex and expressed hope Tuesday that those behind the claims would be exposed in the wake of the woman's notarized confession that she'd never even met the New Jersey Democrat.

"I hope that you will all vigorously go after who was the source and purpose as you did go after the story at the time," he told reporters.

In a notarized statement filed in court, Nexis de los Santos Santana said she was filmed without her knowledge when she claimed that Menendez had paid her to have sex.
